States frequently acquire proof that other states have violated norms. Yet, existing theories do not fully explain how states wield such proof to coerce wrongdoers. Four case studies of nuclear proliferation probe a novel theory of how states coerce norm violators by concealing, sharing privately, or publicizing proof of guilt.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.

Trump tied American jobs to endless wars in the Middle East. Biden should link them to renewed diplomacy.

Tongfi Kim and Andrew Taffer respond to Ketian Zhang’s summer 2019 article, “Cautious Bully: Reputation, Resolve, and Beijing's Use of Coercion in the South China Sea.”

Horizontal nuclear proliferation presents what is sometimes referred to as the "Nth country problem," or identifying which state could be next to acquire nuclear weapons. Nuclear fuel cycle technologies can contribute to both nuclear power generation and weapons development. Consequently, observers often view civilian nuclear programs with suspicion even as research on nuclear latency and the technological inputs of proliferation has added nuance to these discussions. To contribute to this debate, the author puts forth a simple theoretical proposition: En route to developing a civilian nuclear infrastructure and mastering the fuel cycle, states pass through a proliferation "danger zone."

SWJ interview with Nathaniel L. Moir, Ph.D., an Ernest May Postdoctoral Fellow in History and Policy at the Belfer Center for Science and International Affairs, Harvard Kennedy School. Dr. Moir is completing a book manuscript on Bernard Fall for publication.

Domestic politics play a significant role in nuclear decisionmaking under two conditions: when uncertainty over the nature and intensity of a threat is high, and when leaders are incentivized to centralize nuclear policymaking.

Contrary to the conventional wisdom, China is a cautious bully that seeks to balance between the need to establish resolve and the economic cost of coercion, seen through its territorial disputes in the South China Sea.

Liberal market-oriented states are in a natural alliance to preserve and protect a global order that is systematically buttressing states’ embrace of market-oriented norms and values.

What explains the scale and speed of nuclear proliferation? One key factor is the level of competition among suppliers in the market for nuclear materials and technologies. When suppliers form a cartel, fewer countries can acquire what they need for a nuclear weapons program. If great power competition intensifies, suppliers will find it harder to cooperate and nuclear proliferation could accelerate.
